Optronics A57WH 5-Flat to 7-Round Trailer Wiring Adapter, 16 Inch Cable

The Optronics A57WH is a 5-flat to 7-round wiring adapter built to connect a tow vehicle's 7-way round blade trailer connector to a trailer or accessory with a 5-way flat pin connector. It ships with a 16 inch braided cable joining the two connector ends, so towing setups that do not natively match connector styles can be paired without rewiring the vehicle or trailer harness.

The adapter uses a male-to-male connector gender configuration and supports up to 24 volts, making it suitable for standard towing electrical circuits including running lights, turn signals, and brakes where applicable to the connector pins present. It is rated for indoor and outdoor use and is packaged in a sealed anti-static bag. Installation is a straightforward plug-in connection between the vehicle's 7-way round connector and the trailer's 5-way flat connector, with no cutting or splicing required.

This adapter has a universal fit intended for vehicles equipped with a 7-way round blade connector that need to connect to 5-way flat pin trailer wiring. It is backed by a three year warranty.
